摘要: 目的:探讨不同年龄段二叶式主动脉瓣畸形的超声诊断特点。方法:选取71例二叶式主动脉瓣畸形患者为研究对象,按患者年龄分为Ⅰ组20岁9例,Ⅱ组20～39岁15例,Ⅲ组40～59岁31例,Ⅳ组59岁16例。运用超声心动图技术观察各年龄段二叶式主动脉瓣畸形的形态学、血流动力学及心脏形态学变化。结果:随着年龄的增长,主动脉瓣膜钙化,Ⅲ组和Ⅳ组均高于Ⅰ组(P0. 05和P0. 01);主动脉瓣狭窄与关闭不全均呈上升趋势,Ⅱ组、Ⅲ组、Ⅳ组均高于Ⅰ组(P0. 05～P0. 01);升主动脉内径增宽和室间隔厚度增厚,Ⅱ组、Ⅲ组、Ⅳ组高于Ⅰ组(P0. 05～P0. 01),Ⅲ组、Ⅳ组高于Ⅱ组;左心室前后径增大,Ⅱ组、Ⅲ组、Ⅳ组高于Ⅰ组(P0. 05～P0. 01);左心室后壁厚度增厚,各组差异均有统计学意义(P0. 05～P0. 01)。结论:二叶式主动脉瓣畸形的超声诊断结果与患者年龄密切相关,超声心动图对二叶式主动脉瓣的诊断有重要价值。Abstract: Objective: To investigate the ultrasonographic characteristics of bicuspid aortic valve deformity. Methods: Seventy-one patients with bicuspid aortic valve deformity were divided into group Ⅰ( 9 cases， age less than 20 years) ， groupⅡ( 15 cases， age from 20 to 39 years) ，group Ⅲ( 31 cases，age from 40 to 59 years) and group Ⅳ( 16 cases，age more than 59 years) . The morphology，hemodynamics and cardiomorphology of all patients were observed by echocardiography. Results: The aortic valve calcification increased with the growth of age， group Ⅲ and Ⅳ were higher than group Ⅰ( P ＜ 0. 05 and P ＜ 0. 01) . The aortic stenosis and valvularinadequacy showed an upward trend with the age increasing，groupⅡ，Ⅲ and Ⅳ were higher than group Ⅰ( P ＜ 0. 05 to P ＜ 0. 01) . With the growth of age， the ascending aorta inner diameter and thickness of interventricular septum widened and thickened， groupⅡ，Ⅲ and Ⅳ were higher than group Ⅰ( P ＜ 0. 05 to P ＜ 0. 01) ， group Ⅲ and Ⅳ were higher than group Ⅱ( P ＜ 0. 05 to P ＜ 0. 01) . Anteroposterior diameter of the left ventricle increased， groupⅡ，Ⅲ and Ⅳ were higher than groupⅠ( P ＜ 0. 05 to P ＜ 0. 01) . Left ventricular posterior wall of four groups thickened， their differences of which were statistically significant( P ＜ 0. 05 to P ＜ 0. 01) . Conclusions: Bicuspid aortic valve deformity is closely related to the patient's age. Echocardiography has important value in the diagnosis of bicuspid aortic valve deformity.
